This invntion :re1ateslto* impr0Vements in retad holders :'c'0r loofnsand it-is the general object 0f the invention toprovide a device between the reed proper. and the band ra1l L 50 prevent wearing and. ihzifing o:f the latter.

In certain l00ms, particlarly those weaving silk, it is customary to so'lder thereed wires toget'her at their u-pp6r 2LDC11OWBIT ends'. Flat metallic strips Inay be fastened -t0 the 1 aides 0f the wires to present smooth surfaces,

but the upper and 10Wer ends are left rough 01 are o-n1y imperfectly 'sldered. WVhen a reed havingabar tendered rough by protruding:wires is placed in a re edea-p 01 band rail, wearing 0f the latter results. lt iSan important object 0f Our present invention t0 pro- Will :appeat:as the d'escription proceedsoun vide an improvedlpreferably metallic, reed cap betweenthe reed bar and the hand rail t0 -prevent the aforesaid wearing. v

In order t0 -proVide for s1ight variations which existin -the thiekness of the ;reed and it's bar we forn1fthe cap .U-shaped in ;seetion with one of the vertical s'ides bc wedor curvad so as to be cmpressed when the r edis in aerted, the degree 0f compres'siondelaending upon the width ofthe reedbar. j In certaininstancesit-is desirable:to beable t0 vary the :width :0'f Ethe cap and inorder to facilitate such an operation we proVide the upper o1 horizontal part between' thetw o vertica1 sids withkjan initial crim1iexcehdihg' longitudinally of the cap;.p This crirnp affords a line 0f weakness which willpennit the user, by employinga=simple :tool t0 press thesides together t0 -adapt the Cap to narrow slots in thehand rai1. If Sthe slot in the rai'l' is t00 wide, the erim;p ;may ;be fflattened' t0 tl1e wide slot.

With these and other objects inlview Which spread the sides 130 the eorrkagt-width to fit invention resides in the combination and iarrangement o'fparts hereinafte1tdesc'ribed and set fortha'n'the claims.

Referring to Fig. lwehave shown a lay sword 10 supporting a lay 11 having a shuttle race 12. A bac-kstay 13 1nay be* provided wit h a notch 14 to receivea reed holder 15. The .latter may be made as usual Of a longrelative- E1y narrow wooden strip having a vertical s1ot -the rein t0 ;receive the lowerbar of the reed. k

j An extension l6projecting upwardly frorn the lay snpports a band raill7 adjustable as t0 vertical position by lneans of a holt 18 und wvinged nut 19. Theundex sidgeof the band rail has a slot 20 whichmaybe substantially .the sam eas that employed heretofore. The reed R mayfhaVe an upper. bar 21 substantially rect&angular in wertical section and fonmed preferably of metal.

The matter thuS fan describedis of Common -constructlon and forme; no part.;of our present invention. The top of bar 21 may be 1:ough assuggested in Figs. 2 and 4 being ribbed o1 roughened something 1ike a fi1e.

In carrying our invention into eflect -we provide one 01 m01-e ree d caps shown in Fig. 6, having a straight vertical side 31 and a second vertical side- 32 joined theretoby a hori-.

zont-al =connecting section 33. The side 32 may be bowed 011 cu'rved as.at34 tow ard the opposite straight side. The section 33 n1ay be provided with a longitudinal crimp o1 groove 35 and holes 36 may be provided for ION tacks 37 01; otl1er secusing devices whicl1 e tend into tl1e hand rail.

Wlien assemloling the reed cap Will be puslxed upwardly into tl1e groove 20 with tl1e st1aigl1t side 31 to tl1e rear 01' lelt of tl1e slot 20 as viewed in Fig. l so that as tho lay boats up tl1ere Will be yielding of the reed inte1fere with tl1e proper beafiing-in of oho filling. The position of the cap Will be sin1ilar to tl1at shown in Fig. 2, l1e tacks holding tl1e sa1ne in position and tl1e side 89 being bent toward tl1e straight portion 31. 'Il1e reed bar 21 Will then be pushed upwardly between tne two sides to bend the portion 32 forwardly against tl1e front Wall 38 o1 slob 20.

The cap is made of 1netal possessed of s01ne rcsilience and vvl1en tl1e curxed part of tl1e side issfiraightened out against Wall 38 it tends to hold the bar 21 tightly in position. Any 1notion on tl1e part of tl1e reod with respect eo the reed cap Will take place along tl1e interior surfaces of the cap and tl1e latter Will be l1eld against relative 1nove1nent with respect to tl1e cap by tacks 8T, so tl1at abrasion of tl1e interior of oho slot 20 is avoided.

Fig. 4 sl1ows but one cap but in practice We 1nay employ as 1nany as a1e desi1ed to give p1opor stifliness to tl1e reed so filmt the san1e Will beat tl1o filling into tho oloth witl1 a straight line. If desired one sl1ell extencL ing across the full \Vidllh of tl1e 100111 may bc employed.

If upon assembly it is found thatthe slot 20 is slightly wider than the outsido horizontal di1nension of tl1e oap, the groove 01 crin1p 35 1nay be flattened out by 1neans of a nar1ow tool inserted between tl1e sides 31 and 32 as shown in Fig. T, spreading said portions apart so die cap Will fill the groove. If on tl1e other hand, ehe groove is .fonnd so be to-o narrow, a tool such as a pair of pliers suggested in Fig. 5 may be nsed to c01npress die vortical parts of tho cap tow-ard eacl1 otl1er until they are able to fit into tho groove. The 01in1p is therefore seen t0 provide extra inaterial which is available I"or winding tl1e sl1ell 01' provides a line of wealzzxess which Will fa* cilitate reducing tl1e horizontal di1nonsion of the Shell. Wl1ile wo have shown Ehe improved rced o-ap zu; the top only of the 1eod, yet wo (l0 not WlSi1 to be li1nited to "ul1is construction.

Fro1n tl1e foregoing it Will be seon tl1at we l1ave provided a simple reed cap to be interposed between the reed and l;l1e band 1ail to prevent wear of tl1e latae1. It will furtl1er bo seen tl1at a part of the cap is formod Witl1 a cnrved section sulliciently resilient to yield und pennil; encry of reed bar, holding ihn latter tightly in position wilvh respect ;o tl1o 1eed cap. Also, it will be seen tl1at tl1e cap is provided witl1 a cri1np 01 groove along the upper side tl1ereol Wl1lCl ma v bo einplo red -itlmr to widen 0l iacilitalto a nanrowing of il1e cap.

Having tnus described 01 invention it will be seen that changes und modificacions may be 1nade therein by those skilled in the art Withont departing 'f101n t-lJ3 spi1it and scope 01 Elle invention and we do not wisn t 0 bo lin1itcd to tl1e details herein disclosod, but what wo clai1n is:

In a loo1n lay having a liand 1ail with a groove thorein and a reed witl1 a l01'igii3iidinal bar, a reed cap forn1ed of resilient inato1ial located in tho groove and interposoa betwoon tl1e hand rail and tl1e bar and having a portion nonn-ally hold under a stress exoited transvorse of t-l1o plane of the 1eed by illl(3 bar to hold the latter rosiliently in position.

2. In a 100m lay having a hand rail Willi a groovo tl1e1ein and a reed with a longitudinal bar, a reed cap :Eonned 0f resilient 1naceriul looated in tho groove und interposed betweon lho band 1ail und filie bar and l1aving a portion normall hold under a stross cxortcd bransverse of the plane of tl1o reed by tl1e bar to hold tho latte1 resiliently in positi0n, said part being 011 the fronl: side of the reed bar.

3. In a loon1 lay l1aving a l1and rail Willi a groove tl1eroin and a reed with a longitudinal bar, a 1oed Cap f0mned of resiliont 1ncltallic stocl and having two substantially parallel sides attacl1ed together by a connecting section, said section having a longitudinal crixnp dofining an initial line of weakness to facili tate pressing of the two sides of the cap toward each other, the cap baing interposed between die bar and tlie band 1ail.

l-. In a loom lay having a l1and rail witn a groove tl1o1ein and a 1eed Wikh a longitudinal bar, a reed cap substantially U-shaped in section having tl1e opposite sides substantially parallel, and a connecting section attacln ing said sidos together, said section bein 9; 0'f s01ne fonn other than flat to define an initial line of weakness to facilitate bending so (hat tl1e sides n1ay be roadily pressed togother said section also being capable of beging interposed between the bar and band rail.

5. In a 100111 lay, a band rail fo11ned of comparatively soft xnaterial and l1aving a groove in tl1e under side thereof, a reed having a rough bar oft harder material 10 ated in tl1e groove, and a 1netallic reed cap in tl1e groovo and secured to tho l1and rail an:.l interposed between the rougl1 bar and band rail.

6. A reed cap for a lay carried 1eed g'l00"0, said cap being formed of resiliont niaoerial substantially U-shaped in section and having. one of the sides thereof cnrved towar l tln other side and capable of engaging ono sido of tl1e groove and also tne reed to bo hold under strain by the latter and thereby support a resilient mounting for the l001n.

7. A reed cap for a lay car1ied reed groovo said cap having a pair of sides attaclied to gelzl1er by a connocting soction, said connec-ting section having a crimp extending longitudinafly of the cap and providing a line of weakness t0 facilitate pressing' the sides 0f the cap together to fit a smaller groove.

8. A reed cap :Eor a lay carried reed groove, said cap having a pair of lateral members, one 0f which is substantially straight to engage one side of the groove and the other of which is bent toward the straight member engage that sicle of the reed opposite the straight member t-o hold the reed resiliently in position.

9. A reed cap for a lay carried reed groove, said cap having a pair of substantially paralle1 sides attached together by a connecting portion, the latter having a form other than flat to provide a part which when flattened out Will tend separate the sides of the cap.
